MULTIPLE FLOW ROTARY MACHINE Filed NOV. 16, 1965 INVENTOR FIPANK SCOGNQMILLO United States Patent 3,344,745 MULTIPLE FLOW ROTARY MACHINE Frank Scognamillo, 118 Walnut St, Ridgewood, NJ. 07450 Filed Nov. 16, 1965, Ser. No. 508,094 4 Claims. (Cl. 103-4) The invention herein disclosed relates to rotary machines of the bladed type, having rotors carrying sliding blades operating in cylindrical chambers and the general objects of the invention are to provide a practical machine of this type operating with a plurality of flow lines.

These objects have been accomplished by a novel combination of casing having plural inlets or outlets, with a bladed rotor operating therein and a partitioning ring seated in a mid-portion of the rotor and cooperating with the surrounding wall of the cylindrical chamber to form a partition separating opposite end portions of the chamher and the inlets and outlets accordingly.

The accompanying drawing illustrates a present practical embodiment, but structure may be modified within the intent and scope of the invention, as hereinafter defined and claimed.

FIG. 1 is an elevation of one of the machines with the front cover removed to show the sliding blades and partitioning ring in the rotor.

FIG. 2 is a horizontal section on substantially the plane of line 22 of FIG. 1.

FIG. 3 is a broken plan of the rotor.

FIG. 4 is a plan of one of the blades.

FIG. 5 is a plan of a form of partitioning ring.

The body or casing of the machine is shown as made up of an annular wall 7 and flat single plane end Walls 8 and 9, providing a cylindrical opera-ting chamber 10.

The rotor 11 is of cylindrical form having flat single plane ends in flush engagement with the flat end walls and carried by shaft 12, journaled eccentrically in the cylindrical chamber, tangent to the surrounding circular surface.

The rotor is slotted radially at 13 for the sliding vanes or blades 14, which are flush with the flat ends of the rotor and in cooperative relation with the surrounding cylindrical wall.

The rotor is formed with a parallel sided concentric annular groove 15 in the mid-portion of the same and the blades are made with correspondingly placed parallel sided aligning notches 16 in the outer edges of the same.

Slidably and rotatably contained within said groove in the rotor and notched in the blades is a flat faced controlling ring 17, concentric with and in rotatable relation with the surrounding cylindrical wall of the chamber.

This free floating ring seats flush in the rotor at the point of tangency and is wide enough to project as a partition at the widest point of clearance of the rotor in the chamber to form a partition dividing opposite ends of the chamber into separate compartments, FIG. 2.

The separate compartments thus formed may be of diflerent size, according to the location of the partitioning ring in the rotor and they may be provided with separate inlets and outlets or combined in various ways according to the functions of the machine.

FIGS. 1 and 2 show the larger and smaller chambers 18 and 19 as having relative large and small inlets 20 and 21, at one side of the point of tangency and a common discharge outlet 22 at the opposite side of tangency for discharging fluids pumped in a mixed stream, thus to form a proportioning and mixing pump.

FIG. 2 also shows in broken lines how the separate chambers may have independent outlets 23 and 24.

The rotor may be equipped with more than one intermediate partitioning ring, thus to form a greater number of individual compartments than the two shown and outlets and inlets may be provided and be separate or combined, as required.

The partitioning rings may be made in companion, closely fitting parts, as shown in FIG. 5 so as to be readily placed in position in the mounting groove in the rotor.

What is claimed is:

1. A rotary machine comprising in combination,

a casing having a cylindrical chamber defined by a cylindrical peripheral wall and connected parallel end walls,

a shaft journaled eccentrically in said cylindrical chamber, a

a cylindrical rotor on said shaft in tangential relation to the surrounding peripheral wall,

said end walls and rotor having fiat single plane ends in free rotational relation,

said rotor having a deep parallel sided concentric annular groove in the mid-portion of the same,

a flat sided circular partitioning ring concentric with and in rotary sliding relation with said surrounding cylindrical wall and said ring being in free sliding and rotational confinement in said groove in the rotor,

said partitioning ring seating flush in the rotor at the point of tangency and projecting from within the rotor into cooperative relation with the surrounding cylindrical wall at the point of greatest separation of the rotor from the surrounding cylindrical wall,

said free floating ring thereby forming a partition separating compartments in the cylindrical chamber at opposite sides of the same, and

inlet and outlet passages to the respective compartments so formed,

said rotor having longitudinally extending radial slots intersected by said annular groove,

blades slidingly engaged in said slots extending across the annular groove and having notches in the outer edge portions of the same in line with said annular groove,

said ring being slidingly and rotatably engaged in said notches in the blades.

2. The invention according to claim 1 in which'certain of said passages are combined in a single passage.

3. A rotary machine comprising a casing having a cylindrical chamber,

a shaft journaled eccentrically in said cylindrical chamber,

a cylindrical rotor on said shaft in tangential relation to the cylindrical wall and said chamber, having inlet and outlet ports therein on opposite sides of the line of tangency of said rotor,

said rotor having longitudinally extending radial slots and an annular groove intersecting said slots,

blades slidingly engaged in said slots,

said blades extending across said annular groove in the rotor and having notches in the outer edge portions of the same in line with said annular groove, and

a ring slidingly fitting in said annular groove and in the corresponding notches in said blades and slidingly fitting the surrounding cylindrical wall of said cylindrical chamber.

4. The invention according to claim 3 in which said ring is made up of companion closely fitting sections, separable to be engageable over the rotor and blades.
